UN Report warns of ‘Collective Failure” to Act and Meet CO2 emissions gap

Signing up to the Paris Climate Agreement in 2015, world leaders agreed to limit global warming by the end of the century to 1.5 degrees Celsius, ideally, and certainly no higher than 2 degrees C.

But a United Nations report published today says either goal is a long way off. Unless global greenhouse gas emissions fall by 7.6% each year, the world will fail to meet the 1.5°C temperature goal of the Paris Agreement.

Global temperatures are set to rise about 3.2 degrees C by 2100, the report says, bringing catastrophic weather including hotter, deadlier heatwaves and more frequent floods and drought.

Instead of cutting emissions, machines and products released more CO2 in 2018 than ever before, according to the annual Global Emissions report. Last year year, 55.3 gigatons of global CO2 were pumped into the atmosphere, up from 53.5 gigatons in 2017.

Our collective failure to act early and hard on climate change means we now must deliver deep cuts to emissions — over 7% each year, if we break it down evenly over the next decade.

The worst polluters

From 2030, 15 gigatons of CO2 would have to be cut each year. This is roughly the annual emissions of the EU, India, Russia and Japan combined. But time is slowly running out.

Most responsible for the continually increasing emissions is the G20, a group of 20 of the world’s biggest economies, who emit the equivalent of 43 gigatons of CO2 — 78% of global greenhouse gas emissions. Industrialized countries must take the lead here.

How to close the emissions gap

The report names five key areas that will be decisive in the future:

1. At least €1.45 billion ($1.59 billion) annual investment in renewables and more efficient energy use

2. Coal phaseout

3. Decarbonization of transport

4. Decarbonization of industry

5. Increased access to electricity for 3.5 billion people

The number of countries, regions and cities setting goals to go carbon-neutral has risen since September last year from just a handful to about 65.

The European Union, for example, aims to be carbon neutral by 2050. Individual countries including Germany, the UK and France have also set zero-emissions goals.

But how exactly they will achieve this — and how soon — is uncertain. Only a few of the 65 have laid out a timeline for reaching net-zero, according to the report, none of which are countries in the G20.

Fossil fuel production

Fossil fuel production grows globally

Eager to cut out carbon, but unwilling to give up fossil fuels, countries are struggling to rein in emissions. Production of coal, gas and crude oil is rising, and reached its highest level in 2018 at around 37 gigatons.

Some environmental economists have called for a tax on CO2 emissions to incentivize companies to produce energy more sustainably. But the comprehensive introduction of a CO2 price has so far been unsuccessful.

One strategy for closing the emissions gap would see renewable sources make up 85% of the world’s electricity mix by 2050. With higher emissions trees are growing

Major turnaround still possible

On the one hand it’s a matter of having greater ambitions, and on the other hand of implementing them faster. “Energy and transport will be the most important areas.

The report states that technologies for rapid and cost-effective emission reduction have improved, such as the price of solar energy, which can compete with coal on cost.

If the world is to slow down and adapt to global warming, it must acknowledge that “fundamental changes in values, norms, consumer culture and worldviews are inevitable parts of the great sustainability transformation.
