The energy-label approach is automatically reviewed periodically and ensures that employees always choose the most efficient models within each size category. But because each category is assessed separately, it may still include models whose emissions levels exceed your own targets. There is no framework for automatic re-assessment, however, plus in order to offer a well-balanced choice of vehicles per category you need to set separate CO2 limits for each one, which is more labour-intensive.
Therefore, you may wish to combine both of these methods, in which case you focus on your own emissions limits while guaranteeing that only the most energy-efficient models are included in each category. Fuel types have a significant impact on the emissions level, so it makes sense to offer vehicles that run on alternative fuels. Biogas which has the same composition as CNG but is produced through the fermentation of biomass achieves even better results. Last but not least, hydrogen also produces zero carbon emissions but this is not yet a feasible option for business purposes for reasons of expense and lack of refuelling stations.
Besides the choice of vehicle and fuel type, drivers themselves play a key role in the actual emissions level in practice.
To make employees aware of the impact of their driving behaviour on the CO2 emissions level, share your insights with them in the form of online fuel-consumption reports or dashboards, and organise training sessions to encourage fuel-efficient driving. The USA has emitted most to date: more than a quarter of all historical CO 2 : twice that of China which is the second largest contributor. In contrast, most countries across Africa have been responsible for less than 0.
What becomes clear when we look at emissions across the world today is that the countries with the highest emissions over history are not always the biggest emitters today. Reductions here will have a relatively small impact on emissions at the global level — or at least fall far short of the scale of change we need.
This creates tension with the argument that the largest contributors in the past should be those doing most to reduce emissions today. This is because a large fraction of CO 2 remains in the atmosphere for hundreds of years once emitted. This inequality is one of the main reasons which makes international agreement on who should take action so challenging. These emissions are adjusted for trade. To calculate consumption-based emissions we need to track which goods are traded across the world, and whenever a good was imported we need to include all CO 2 emissions that were emitted in the production of that good, and vice versa to subtract all CO 2 emissions that were emitted in the production of goods that were exported.
In the interactive map we see the emissions of traded goods. We see quite a regional East-West split in net exporters and importers: most of Western Europe, the Americas, and many African countries are net importers of emissions whilst most of Eastern Europe and Asia are net exporters. You can find these figures in absolute tonnes of CO 2 and per capita terms for each country in the Additional Information section.
In the interactive charts you can compare production- and consumption-based emissions for many countries and world regions since the first data is available in Individual maps of consumption-based annual and per capita emissions can also be found in the Additional Information which follows this post.
We see that the consumption-based emissions of the US are higher than production: In the two values were 5. This tells us that more CO 2 is emitted in the production of the goods that Americans import than in those products Americans export. On a per capita basis, the respective measures are 6. A difference, but smaller than what many expect. Whilst China is a large CO 2 emissions exporter, it is no longer a large emitter because it produces goods for the rest of the world.
This was the case in the past, but today, even adjusted for trade, China now has a per capita footprint higher than the global average which is 4. In the Additional Information you find an interactive map of how consumption-based emissions per capita vary across the world. These comparisons provide the answer to the question whether countries have only achieved emissions reductions by offshoring emissions intensive production to other countries.
There are some countries where this is the case. Examples where production-based emissions have stagnated whilst consumption-based CO 2 steadily increased include Ireland in the early s ; Norway in the late s and early s; and Switzerland since On the other hand there are several very rich countries where both production- and consumption-based emissions have declined.
These countries have achieved some genuine reductions without outsourcing the emissions to other countries. Emissions are still too high in all of these countries, but it shows that genuine reductions are possible.
In most countries emissions increased when countries become richer , but this is also not necessarily the case: by comparing the change in consumption-based emissions and economic growth we see that many countries have become much richer while achieving a reduction of emissions.
Countries which are net importers are shown in red and given as positive values , with net exporters shown in blue given as negative values. In the interactive map we see how consumption-based CO 2 emissions vary across the world. In the visualization we show how consumption-based emissions corrected for population size — emissions per capita — varies across the world. There are two parameters that determine our collective carbon dioxide CO 2 emissions: the number of people, and quantity emitted per person.
We either talk about total annual or per capita emissions. They tell very different stories and this often results in confrontation over who can really make an impact: rich countries with high per capita emissions, or those with a large population. To help us understand the global distribution of per capita emissions and population, we have visualized global CO 2 emissions by 1 World Bank income group and 2 by world region.
Since total emissions are equal to per capita emissions multiplied by the number of people, the area of each box represents total emissions. When aggregated in terms of income, we see in the visualization that the richest half high and upper-middle income countries emit 86 percent of global CO 2 emissions.
The very poorest countries home to 9 percent of the global population are responsible for just 0. This provides a strong indication of the relative sensitivity of global emissions to income versus population. Even several billion additional people in low-income countries — where fertility rates and population growth is already highest — would leave global emissions almost unchanged.
At the other end of the distribution however, adding only one billion high income individuals would increase global emissions by almost one-third. Note here that the summary by income is on the basis of country income groupings, rather than that of individuals. The richest of the global population would be responsible for an even larger share of global emissions.
When aggregated by region we see that North America, Oceania, Europe, and Latin America have disproportionately high emissions relative to their population. North America is home to only five percent of the world population but emits nearly 18 percent of CO 2 almost four times as much. Asia and Africa are underrepresented in emissions.
Asia is home to 60 percent of the population but emits just 49 percent; Africa has 16 percent of the population but emits just 4 percent of CO 2. This is reflected in per capita emissions; the average North American is more than 17 times higher than the average African. This inequality in global emissions lies at the heart of why international agreement on climate change has and continues to be so contentious.
And, when these plants and animals decompose, organisms within the soil respire to produce energy and emit more CO2 into the atmosphere. Nature, as nature tends to do, keeps most of these emissions in balance. Plants absorb CO2 through photosynthesis, and oceans absorb just about as much carbon dioxide as they let off. Carbon cycles through our air, water, and soil in a continuous process that supports life on earth.
When we extract, refine, transport, and burn fossil fuels like coal, natural gas, and oil, we release extra carbon and other greenhouse gasses into the atmosphere. We also cut down large expanses of CO2-absorbing trees to make way for agriculture and new developments, or collect lumber to create new products.
When these trees burn or decompose, they emit even more CO2. By removing forests, we also effectively remove the natural systems that absorb and store carbon. Long story short, CO2 is one of the greenhouse gases that absorbs radiation and prevents heat from escaping our atmosphere. As with most things in life, there are two main ways to fix a problem. The first, and safest option, is to avoid the situations that cause it in the first place.
When you apply this thinking to carbon emissions, it means you can either lower your carbon footprint, or offset it. On the personal level, there are many ways to lower your impact.
Bike to work make your commute easier here , eat less meat, buy less stuff, the list goes on and on. When companies get involved, the impact gets even bigger. If you nerd out on companies doing cool things like we do , check out some of our brands and their stories here!
Both individuals and businesses can join organizations that implement energy efficiency, reforestation, and renewable energy programs to offset a portion or all of the carbon emissions created.
Although EarthHero works hard to give our customers access to sustainably made products, we recognize that transporting those products to you comes with its own set of concerns.
Through Carbonfund. And these offsets make us a carbon-neutral company. They help local ecosystems too, by preserving wildlife habitats, improving soil quality, and adding water storage capabilities to lands across the US. From turning out lights when you leave a room to commuting via bus or bike, you can reduce your footprint.
Take a look at how you shop, and make a conscious effort to make more sustainable choices. Buy products that make you happy, but make them last. When you do shop, shop with companies that take a stand to reduce their own footprint. When we overload it with too much of any one thing, however, it can start to lose its balance.
