Environmental Impact & Sustainability of Construction Punit Sharnagat
Construction projects can have significant local and global environmental impacts. Locally, they can cause land clearance and loss of biodiversity, noise and air pollution, and urban flooding. Globally, factors like global warming, resource usage, and ozone layer depletion are impacted. Buildings are responsible for around half of UK greenhouse gas emissions and 10% from producing materials. The construction industry accounts for 22% of India's CO2 emissions. To mitigate impacts, planning must focus on using non-toxic, low embodied energy, recyclable, and local materials. Macro, meso and microscopic planning that incorporates sustainability is key to reducing environmental effects.
The document summarizes the Environment Protection Act of 1986 in India. It was established after the Bhopal gas tragedy to fill gaps in existing environmental laws. The act aims to implement UN decisions on protecting the human environment, coordinate regulatory agencies, provide deterrents for endangering health, and ensure sustainable development. It gives the central government powers to establish authorities, enforce standards and restrictions, and prescribe penalties for non-compliance.
This document reviews pathways for producing green hydrogen, ammonia, and methanol from renewable energy sources to enable decarbonization of the shipping industry. It discusses methods for producing green power via renewable energy, then using that green power to electrolyze water and produce hydrogen. The hydrogen can then be used to produce ammonia via the Haber-Bosch process or methanol from CO2. While these green fuels have potential to decarbonize shipping, production costs are currently higher than conventional fuels. Improving renewable energy and electrochemical fuel production technologies could help reduce costs and ensure adequate supply of low-carbon marine fuels to meet emissions reduction goals.
The document discusses energy efficiency measures in the shipping industry and barriers to their adoption. It identifies key stakeholders in ship operation and their influence on implementing energy efficiency. A literature review found the most common barriers include lack of information, financial constraints, technical risks, and lack of crew awareness/training. A pilot survey was conducted to validate questionnaires on barriers. The main survey collected data from 91 stakeholders in Bangladesh and Malaysia on their influence level on 18 energy efficiency measures. The findings show measures with very high influence levels include improved voyage planning, speed optimization, hull cleaning, and propeller cleaning.
The document discusses the environmental dimensions of a ship's life cycle from design through construction, operation, and scrapping.

Black carbon emissions from marine diesel enginesTechFinland
Päivi Aakko-Saksa from VTT gave a presentation on reducing black carbon emissions from marine diesel engines. She explained that shipping accounts for a significant portion of emissions like sulfur oxides, nitrogen oxides, and black carbon. Black carbon is the second strongest human-caused climate forcing agent after carbon dioxide. The presentation discussed how fuel choices like liquefied natural gas and methanol can substantially reduce black carbon emissions. Exhaust treatment technologies like particulate filters when paired with clean distillate fuels can also lower black carbon. Ultimately, combining renewable or electro fuels with appropriate exhaust controls or moving to full electric and hydrogen-powered solutions sourced from renewable energy could achieve near-zero emissions.
This document proposes constructing a near-shore confined disposal facility (CDF) to manage contaminated sediments from dredging a harbor in California. Sediments contain DDT, PCBs and a discovered Japanese submarine. A CDF would safely contain pollutants, beneficially reuse sediments for port construction, and have lower environmental impact and cost than alternatives like landfilling or treatment. Best practices like silt curtains and slow dredging would minimize water pollution. Air impacts from dredging and additional traffic would be reduced through recommendations like cleaner fuels and incentives for public transit. The submarine's historical value requires careful recovery. Stakeholders have differing priorities that a CDF could balance by providing a compliant, economical, sustainable and efficient solution.
