Below is the latest data (2024) for which sectors are responsible for most greenhouse gas emissions.

As you can see from the above, power generation was responsible for 15.6 GtCO2e (up 1.2% from 2023) and transport was responsible for 8.4 GtCO2e (up 0.91% from 2023)

Here is the reality, we have the technology and know-how to radically reduce emission from both these sectors. We just have to move faster!

Electricity Generation

The team at Ember has just released data for 2025 in their report entitled From OECD to emerging markets: fossil power’s global decline has begun.

They say:

Rapid solar and wind scaling is actively displacing thermal generation. OECD fossil generation has peaked while systematic decommissioning of coal-fired power plants is under way across most member states. This shift is now extending beyond the OECD, with fossil generation falling in major emerging economies for the first time this century outside the COVID-affected year of 2020.

This graphic from the report show's this clearly in OECD nations:

The report also singles out China, which is solidifying its position as the world's first Electrostate and India.

Clearly we have turned the corner now that renewable energy is readily available. Also from Ember:

Transportation

The data on this sector is also nothing short of remarkable as the world turns to electric vehicles. The war in the middle east, with its accompanying oil shocks has just accelerated this trend.

Nowhere is this more visible than across these six regions, (data displays monthly sales of new passenger cars up to March 2026). The full dataset tracking the electric car revolution across all reporting countries can be found here.

Now we need to go faster

Now that we have proven that there are viable alternatives to fossil fuel driven transport and power generation, there is no excuse not to accelerate the rollout of these technologies as fast as we can!

Why do we need to do this?

Because we know if we do, we can change the emissions trajectory we are on!

Take a look:

Of course, as you can see from the above, there are other actions we need to take to get global heating below 2ºC but by slamming the brakes on these two high emitting sectors, using our current technology, will go a long way to achieving this goal.

We need to put as much pressure as we can on elected officials everywhere to make this transition as easy and as fast as possible.
