Context:
Emissions from oil have risen most during last one year showing overall global carbon emission reached all time high.
Key findings:
- Global emissions from oil rise steeply in 2023 compared to 2022 pushing back coal and gas
- Reason – Canada’s destructive wildfire season – 6 to 8 times than average
- more than 40% global emissions required to be cut by 2030 as per Paris agreement targets.
- The Climate Action Tracker says – warming of 1.8°C still well above 1.5˚C.
Global Carbon Project Report:
- Part of Future Earth in 2014
- Prepared every year
- By a global consortium of scientists
- Establish a common understanding of the Earth carbon cycle
- To tackle the problem of rising concentrations of greenhouse gases.
- Dominant greenhouse gases — carbon dioxide, methane, and nitrous oxides.
The Climate Action Tracker:
- Independent scientific project
- Tracks government climate action and measures according to Paris Agreement.
- Collaboration of Climate Analytics and New Climate Institute,
- Quantifies and evaluates climate change mitigation targets, policies and action.
- Calculates global warming consequence and emissions gaps

Previous Year Question
Consider the following;
1. Carbon monoxide
2. Nitrogen oxide
3. Ozone
4. Sulphur dioxide
Excess of which of the above in the environment is/are cause(s) of acid rain?
[UPSC Civil Services Exam – 2022 Prelims]
(a) 1, 2 and 3 only
(b) 2 and 4 only
(c) 4 only
(d) 1, 3 and 4 only
Answer: (b)
Explanation
Acid Rain refers to rain or any other form of precipitation that has a higher level of hydrogen ions .Oxides of sulphur and nitrogen which are acidic in nature are responsible for acid Rain. Thus carbon dioxide and ozone does not create acid rain.
