Oxfam has recently published a report titled “Tightening the Net” just a few months ahead of the UN climate talks in Glasgow.
Key Findings of Report
- ‘Net zero’ carbon targets that many countries have announced maybe a “dangerous distraction” from the priority of cutting carbon emissions.
- “Land-hungry ‘net zero’ schemes could lead to
- an 80 per cent rise in global food prices.
- more hunger.
- allowing rich nations and corporations to continue “dirty business-as-usual.
What is the meaning of Net Zero?
- A state in which a country’s emissions are compensated by absorption and removal of greenhouse gases (GHGs) from the atmosphere is called Net Zero State.
- Net-zero is also referred to as carbon-neutrality.
- It does not mean that a country would bring down its emissions to zero.
How is it Different from Gross-Zero?
Gross Zero |
Net Zero |
A state where there are no emissions at all. |
Emissions are compensated by absorption or removal of equivalent GHGs |
Very hard to achieve. |
Promised by many countries. |
More Beneficial for the environment and ultimate goal. |
Less beneficial and may distract the world as per IPCC report. |
How Net Zero is Achieved?
- By creating carbon sinks by growing forests.
- Until recently, the Amazon rainforests in South America, which are the largest tropical forests in the world, were carbon sinks.
- But eastern parts of these forests have started emitting CO2 instead of absorbing carbon emissions as a result of significant deforestation.
- A country may also have negative emissions if the absorption and removal exceed the actual emissions.
- Bhutan has negative emissions because it absorbs more than it emits.
- Until recently, the Amazon rainforests in South America, which are the largest tropical forests in the world, were carbon sinks.
Which Countries have Recently Announced Net-Zero Targets?
- The New Zealand government passed the Zero Carbon Act in 2019.
- It committed to zero carbon emissions by 2050 or sooner to meet its Paris climate accord commitments.
- In 2019, the UK passed legislation to reduce its net emissions of GHGs by 100 per cent relative to 1990 levels by the year 2050.
- Recently, the USA also announced its plans to cut its greenhouse gas emissions by at least 50 per cent below 2005 levels by 2030.
- John Kerry launched a bipartisan organisation called World War Zero in 2019.
- He is the USA’s climate envoy and considered one of the chief architects of the Paris Climate agreement
- World War Zero aims to bring together unlikely allies on climate change and with the goal of reaching net-zero carbon emissions in the country by 2050.
- John Kerry launched a bipartisan organisation called World War Zero in 2019.
- “Fit for 55” plan of European Union: The European Commission has asked all of its 27 member countries to cut emissions by 55 per cent below 1990 levels by 2030.
- Last year, China set a target of becoming net-zero by the year 2060.
- It would also not allow its emissions to peak beyond what they are in 2030.
Why are Net Zero Targets of Less Utility?
- To tackle the challenge by planting more trees, about 1.6 billion hectares of new forests would be required by 2050.
- The world needs to cut emissions by 45 per cent by 2030 from 2010 levels to limit global warming below 1.5°C.
- The sharpest cuts should be made by “the biggest emitters.”
- Current Net Zero Targets will only lead to a 1 per cent reduction by 2030.
- It will add extra pressure on already limited land resources.
- To tackle only energy sector emissions, a land area nearly the size of the Amazon rainforest is required.
- It is equivalent to a third of all farmland worldwide.
- Using only land-based methods may push the food prices up by 80 per cent by 2050.
- To tackle only energy sector emissions, a land area nearly the size of the Amazon rainforest is required.
Way Ahead
- Nations should shift towards renewable energy sources.
- Focus on cutting the carbon sources rather than mere mitigation through forest reserves can help.
- Marine Farming and Blue Economy may help in reducing the pressure on land resources.
